Get the raw sound of punk, alt rock, and metal under your boots.

Knuckles '92 Dual Rec Amplifier delivers the searing high-gain tone that powered legendary punk, alt rock, and metal bands from Foo Fighters and Incubus to Nevermore, Dream Theater, and more.

Giving you six classic mic and speaker pairings, built in TS-style OD/boost, and noise gate, Knuckles puts the authentic genre-defining sound of one of the world's most ferocious high-gain amps under your boots.

Plug into the California King of High Gain

Whether you seek the gritty power chords of punk and alternative anthems by the likes of Dave Grohl and Incubus or the complex aggression of Nevermore and Dream Theater, Knuckles ‘92 puts one of the most versatile multi-channel amps ever made right on your pedalboard.

Explore a Range of Rectifier Tones
